BAT System Description for NIST LRE 2015
Original language description
In this work, we have described our efforts in the NIST LRE 2015. The most difficult part of this evaluation was to deal with limited amount of data and the results show that the proper analysis in this direction is necessary. We have built over 20 systems for this evaluation. We have experimented with de-noising NN, automatic unit discovery, different flavors of phonotactic systems, backends, sizes of ivector systems, feature sets, BN features or frame level language classifiers. We used up to 6 systems in the fusion. The performance of our best system reached Cavg of 16.9% on the fixed training data condition and 13.9% (11.9% after post-evaluation analysis) on the open training data condition.
